Hi Pam,
My institution has an age range of 18-60. I have experienced the same as you have, having some students right out of high school and others are of retiring age. I generally have the most challenges with those students right out of high school. The students right out of high school still seem to be a little immature and somewhat unfocused. I typically see right after the first test if the score is low, the student right out of high school seems to become more serious. At times, I have even had to have conversations about getting foucused.
